This frequency band has been allocated to the mobile service, the fixed service and the fixed-satellite service on a primary basis in all three regions by ITU-R Radio Regulations.Wireless Access Systems are broadband radio systems which can be deployed either inside or outside buildings, usually in geographically limited areas. Broadband RLAN, a subset of WAS, are the major type of equipment deployed today and are predominantly used inside buildings. Typical WAS/RLAN include public and private applications offered in homes, schools, hospitals, hotels, conference centres, railway stations, airports, shopping centres, etc. These types of applications may thus be considered to fall into the ITU-R categories nomadic wireless access (NWA) or mobile wireless access (MWA) REF _Ref50998156 \r \h [10]. They are typically intended for connections between traditional business products such as PC, laptops, workstations, servers, printers and other networking equipment as well as digital consumer electronic equipment in the wireless home network environment. RLAN thus remove the need for physical connection of the above devices. RLAN utilise low power levels because of the short distance nature of inside building operation. Most of the existing RLAN and similar broadband data transmission systems are currently operating in the ISM frequency bands. In order to ensure high reliability and higher data transfer rates RLAN, however, require a more predictable sharing environment. Therefore, other frequency bands have been identified which are more suitable than the ISM bands for these kinds of services. More detailed information regarding broadband RLAN applications which are used worldwide can be found in Recommendation ITU-R M.1450 REF _Ref29909438 \r \h [5].BACKGROUND The results of detailed compatibility and sharing studies within CEPT taking into account the existing radio services can be found in ECC Reports 302 REF _Ref42601264 \r \h \* MERGEFORMAT [4], 316 REF _Ref30744564 \r \h \* MERGEFORMAT [6] and in complementary studies performed in parallel with the public consultation on this ECC Decision in order to further assess the in-band Power Spectral Density (PSD) for VLP devices and out-of-band emission limits below 5935 MHz for LPI and VLP devices. This technical assessment were also the basis for the response to the EC Mandate on 6 GHz WAS/RLAN in CEPT Report 73 (2019) REF _Ref40871310 \r \h \* MERGEFORMAT [7] and draft CEPT Report 75 REF _Ref40871320 \r \h \* MERGEFORMAT [8]. As a consequence of these studies, the following use cases and related conditions were identified for use by WAS/RLAN in the bands 5945-6425 MHz:Low power indoor (LPI) use, maximum mean 200 mW e.i.r.p., with no outdoor use allowed;Very low power (VLP) portable use, maximum mean1 25 mW e.i.r.p., that may both operate indoor and outdoor. The e.i.r.p. requirements assumed generic WAS/RLAN systems. Those systems can be described by two common configurations: centralised systems, where multiple devices are connecting to an access point (AP), and non-centralised systems, where multiple devices communicate directly in a small area on an ad-hoc basis. Consideration of use cases with powers higher than those described in this Decision including for outdoor use would require further investigations.LPI use is intended to be permanently in buildings, in aircraft or in trains. The outdoor use of the frequency band is restricted to the VLP usage because of the protection requirements of other radio services. The VLP outdoor use is intended to cover short range applications for small area direct communications. VLP devices can operate in the frequency band 5945-6425 MHz throughout CEPT taking into account operations of Urban Rail Intelligent Transport Systems (ITS). This approach is based on the conclusions contained in CEPT Report 73 and further elaborated on in CEPT Report 75 REF _Ref41290254 \r \h \* MERGEFORMAT [8].It should be noted that the -45 dBm/MHz OOB limit below 5935 MHz for VLP would allow VLP initial market to take up. CEPT also agreed that this OOB limit should be valid in time only until 31 December 2024 and be re-examined with regard to an opportunity to relax it based on the real IEEE and DSSS Urban Rail interference situation. In absence of the justified evidence, a value of -37 dBm/MHz, for the OOB limit below 5935 MHz, will be adopted from 1 January 2025.ETSI has published a System Reference Document TR 103 524 REF _Ref40871412 \r \h [2] and is currently working on the development of a draft harmonised standard ETSI EN 303 687 REF _Ref40871589 \r \h [9] where the CEPT studies and resulting use cases will be considered.As there are concerns regarding the protection of national implementations of the fixed service, especially regarding the short-term protection criterion, national administrations should support an effective enforcement of the indoor restriction for LPI in order to maintain an adequate protection of the fixed service.Finally, this ECC Decision may be reviewed in order to address the results of the relevant activities, where considered appropriate, to enhance its implementation status in CEPT.REQUIREMENT FOR AN ECC DECISIONThe allocation or designation of frequency bands for use by a radio service or system under specified conditions in CEPT member countries is laid down by law, regulation or administrative action. ECC Decisions are required to deal with the licence related matters and for the carriage and use of equipment throughout Europe. The harmonisation on a European basis would support the Directive 2014/53/EU of the European Parliament and of the Council of 16 April 2014 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity REF _Ref525819411 \r \h [1]. A commitment by CEPT member countries to implement an ECC Decision will provide a clear indication that the required frequency bands will be made available on time and on a European-wide basis.ECC Decision of 20 November 2020 on the harmonised use of the frequency band 5945-6425 MHz for Wireless Access Systems including Radio Local Area Networks (WAS/RLAN) (ECC/DEC/(20)01)“The European Conference of Postal and Telecommunications Administrations,consideringthat there is a need to harmonise additional spectrum for the implementation of Wireless Access Systems including Radio Local Area Networks (WAS/RLAN);that the frequency band 5945-6425 MHz has been allocated to the mobile service, the fixed service (FS), and the fixed-satellite service (FSS) on a primary basis in ITU Region 1 and in the European Common Allocation Table (ECA);that the frequency band 6650.0-6675.2 MHz is covered by RR footnote 5.149, which urges administrations “to take all practicable steps to protect the radio astronomy service (RAS) from harmful interference” and that the appropriate measures to protect the RAS stations may be defined on a site-by-site basis at national level;that ECC/DEC/(08)01 harmonises the use of the frequency bands 5875-5935 MHz for safety-related Intelligent Transport Systems (ITS);that compatibility studies in ECC Report 302 and ECC Report 316 have shown that sharing between WAS/RLAN and FSS earth stations and terrestrial FS deployments in the band 5945-6425?MHz is feasible under certain conditions;there is no out-of-band emissions (OOBE) limit included in this ECC Decision, to protect adjacent incumbents operating above 6425?MHz, as the same incumbents will be operating co-channel with WAS/RLAN below 6425?MHz;that the conditions provided in Table 1 of Annex 1 of this ECC Decision also apply to WAS/RLANs used inside trains and aircraft; train operators, manufacturers and train owners should consult the relevant national or regional railway regulatory bodies before installing and using WAS/RLAN on board trains;that national administrations should support an effective enforcement of the indoor restriction for LPI in order to maintain an adequate protection of the fixed service that OOBE limit for VLP should be valid in time only until 31 December 2024 and be re-examined with regard to an opportunity to relax it based on the real IEEE and DSSS Urban Rail interference situation.
